SPECIFICATXON forming part of Letters Patent No. 67 6,121, dated June11, 1901. Application led .Tune 20, 1900. Serial No. 20,979. (No model.)

To @ZZ whom t may concern:

Be it known that I, JACOB J. BUSENBENZ, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a new and useful Improvementin Reservoirs for Vapor-Lam ps, of

Which the following is a specification.

My invention relates to improvements in the construction of reservoirsfor containing volatile hydrocarbon oils and from Which the oil isautomatically fed to a burner, and While my improvements are moreparticularly adapted for the gasolene reservoirs of incandescentvapor-lamps they are not to be limited to any such specially-limitedconnection.

Hitherto it has been usual to provide res'- ervoirs of the class towhich my invention relates With an outlet-tube extending from the -baseor lower part of the interior; but this construction has been foundobjectionable, particularly in connection With incandescent vapor-lampsemploying small burner-openings. The gasolene frequently contains smallparticles of foreign substances, or corrosion of the interior surface ofthe reservoir may cause metallic particles to drop therefrom, which Whencarried through thefeed-tube to the burner-opening will tend to clog thelatter or, if burned, may effect discolorationA had for the purpose ofcleaning it when de-V sired.

The draWinO shows m f im roved reservoir u ou 1n vertical section.

Ais the body portion of the reservoir, which for purposes ofconstructionmay be in two parts, brazed or otherwise secured together at a to form aliquid-tight joint. Extending upward through the base of the bodyportion is alfeed-tube B, brazed or otherwise.

secured at b and provided at its upper end with a screw-thread c.Fitting the upper en d of the body portion is a cover C, having acentral opening d to f1tclosely over the upper end portion of the tubeB. The cover is fastened in place by means of a knob or the like'D,which containsa threaded socket e to engage the upper projectingthreaded end of the feed-tube.- In the cover is a fillingopening f,provided with the usual screw plugf, and also in the cover is a floatdevice g to indicate when the receptacle is filled. The cover should fitclosely upon the body portion of the reservoir and is tightened rigidlyin place by means of the knob D. Near its upper end the feed-tube isprovided with an opening h for a wick E, which at one end portion restsin the bottom of the receptacle and extends through the opening h downthe interior of the tube B, preferably to a point belovsT the base ofthe reservoir.

The gasolene or other volatile oil iu the res' ervoir is raised bycapillary action in the Wick and iiows into the tube, this operationbeing aided by the siphoningaction due to the extension of the Wick inthe tube below the level ofthe liquid in the reservoir. No particles offoreign material which might tend to clog` the burner-opening will risethrough the wick E, so that only the pure liquid will be fed into thetube. As the Wick extends to the base of the reservoir, the latter maybe emptied of `cleanse the interior from time to time of all suchdeposits or of other foreign particles that may have found their Wayinto the reservoir.

.T he removable cover C offers ready facilities for reaching all partsof the interior for the purposel of cleaning the same.

While I prefer to construct my improvements throughout as shown anddescribed, they maybe modified in the matter of details of constructionWithout departing from the spirit of my invention as defined by theclaims.

What I claim as new, and desire to secure by Letters Patent, is-

l. The combination with a reservoir for liq- "nid hydrocarbon, of afeed-tube extending through the base of the reservoir and beyond the topthereof and having a screw-thread at its upper end, a cover fitting thetop ofthe reservoir having a central aperture receiving the upper end ofthe tube, a cover-securing IOO device engaging the-thread on the tube,and andv having an opening tting the said tube, Io Y; a Wick in thereservoir entering the tube and and a knob D screwed upon said tube andconducting the liquid to the latter by capiifastening the cover inplace, substantially as lary action. set forth. 5 2.
